Class DefaultExprDef

java.lang.Object

oracle.jbo.common.DefaultExprDef

All Implemented Interfaces:

ExprDef

public abstract class DefaultExprDef
extends java.lang.Object
implements ExprDef

An abstract implementation of an ExprDef. The DefaultExprDef adapts a general GroovyCodeSource for us with the ADF groovy compiler/evaluator. Libraries that do not define a proper ADF ExprDef implementation may create a DefaultExprDef to use the ADF groovy compiler/evaluate. The DefaultExprDef provides default implementations of many of the ADF ExprDef APIs that may not be appropriate for more general purpose groovy evaluation.

DefaultExprDef

public DefaultExprDef()

Method Detail

getPath

public java.lang.String getPath()

Description copied from interface: ExprDef

A dot separated path that may be used to lookup the ExprDef within the ExprDef's owning compnent. See ComponentOperationsManager#findExprDef.

Specified by:

getPath in interface ExprDef

getExpressionSource

public java.lang.String getExpressionSource()

Description copied from interface: ExprDef

The source string of the expression.

Specified by:

getExpressionSource in interface ExprDef

getTrustMode

public ExprEval.TrustMode getTrustMode()

Description copied from interface: ExprDef

The trust mode for the expression.

Specified by:

getTrustMode in interface ExprDef

hasReturn

public boolean hasReturn()

Description copied from interface: ExprDef

If the expression has a return value.

Specified by:

hasReturn in interface ExprDef

getExprIdentifier

public java.lang.String getExprIdentifier()

Description copied from interface: ExprDef

A unique identfier for the expression.

Specified by:

getExprIdentifier in interface ExprDef

getCacheKey

public java.lang.String getCacheKey(java.lang.String exprStr)

Description copied from interface: ExprDef

The key to be used for caching compiled expression instances.

Specified by:

getCacheKey in interface ExprDef

Returns:

a cacheKey. If null then the compiled expression will not be cached.

isOperationsExpression

public boolean isOperationsExpression()

Description copied from interface: ExprDef

If the expression defines operations.

Specified by:

isOperationsExpression in interface ExprDef

getScriptClassName

public java.lang.String getScriptClassName(java.lang.String exprStr)

Description copied from interface: ExprDef

Returns the name used for the expression class.

Specified by:

getScriptClassName in interface ExprDef

getExpressionClassName

public java.lang.String getExpressionClassName()

Description copied from interface: ExprDef

Returns the name used for the expression class.

Specified by:

getExpressionClassName in interface ExprDef

getTypeCheckedMode

public ExprEval.TypeCheckedMode getTypeCheckedMode()

Description copied from interface: ExprDef

Returns whether the expresion should be type checked when type checking is enabled for the groovy compiler.

Specified by:

getTypeCheckedMode in interface ExprDef

Returns:

ExprEval.TypeCheckedMode.always if the expr should always be type checked ExprEval.TypeCheckedMode.never if the expr should never be typ checked ExprEval.TypeCheckedMode.defer if type checking is dependent upon the application configuration

getOwnerType

public OwnerType getOwnerType()

Description copied from interface: ExprDef

Returns the type of object that owners the expression class.

Specified by:

getOwnerType in interface ExprDef

getCodeSource

public CodeSource getCodeSource()

Description copied from interface: ExprDef

Returns the code source that contains the code for this expression.

Specified by:

getCodeSource in interface ExprDef

getTriggerType

public java.lang.String getTriggerType()

Description copied from interface: ExprDef

Return the trigger type.

Specified by:

getTriggerType in interface ExprDef

Returns:

null if this is not a trigger expression.

supportsAnnotation

public boolean supportsAnnotation()

Description copied from interface: ExprDef

Indicates whether ADF can use an expression annotation to select the expression method for invocation. This is required for some internal expression usages that are not uniquely identified by the annotation. In those cases the framework will use the more unique expression identifier to select the method invocation target.

Specified by:

supportsAnnotation in interface ExprDef

getProperty

public java.lang.Object getProperty(java.lang.String name)

Specified by:

getProperty in interface ExprDef

getGroovyCodeSource

public abstract groovy.lang.GroovyCodeSource getGroovyCodeSource()
